Chronic Obstructive Pulmonary Disease, or COPD for short, is a lung disease that affects millions of people. COPD includes diseases such as emphysema and chronic bronchitis. A person with COPD may have either emphysema or chronic bronchitis, but many have both. Some people with COPD may also have asthma-like symptoms, such as wheezing.
